Question How to check if someone on a shared wifi is trying to hack my account

[travistee]

I use Nordvpn most of the time so that should be ok.

If I'm not using the VPN is there a way to see if someone is trying to hack into my account?

Sometimes the system gets very slow. speedtest.net show it goes down from 18 to 2. I suspect some sort of program is running that may
be trying someway of hacking. Is that possible? What sort of program would use that much bandwidth? It seems much more than watching videos.
Would a high resolution monitor be the possible cause?

Is there a program that can tell me what the activity is?

I installed glasswire. It shows a graph of the usage but tells me nothing about where it is coming from.

what do you mean coming from. look at what app is consuming bandwidth.

I see the yellow and blue bars but I don't see where I can see which app is using bandwith.
I see the firewall that allows apps to be blocked but thats not what I want.

Actually I'm interested in which users on the wifi are consuming bandwith.

Do you know of an app that can do that, or how I can do that in this one?
